Ru.

公知のコンクリートポンプ車の場合、飛沫防止装置はそのほとんどが、材料供給 容器のポンプ側に固定取付けられた薄板箱として形成されている。これにより、 コンクリート送出時に、材料供給容器内で発生するコンクリート飛沫が機械範囲 に達しない。しかし、薄板箱の構造高さが充分である場合だけしか、効果的な飛 沫防止が達成できないことが判った。これは他方では、シャシ−に支持された分 配ブームの下方に充分な空きスペースを必要とする。この空きスペースは特に大 型の分配ブームの場合には常に供されるとは限らない。走行状態において、材料 供給容器の充填開口はしばしば、ゴムマットして形成されたホッパーカバーによ って閉鎖される。それによって、走行時にコンクリートの飛沫が飛び散ったり、 例えば太陽光線照射によってコンクリートが早く硬化する。In the case of known concrete pump trucks, most of the splash prevention devices are installed at the material supply. It is designed as a sheet metal box that is fixedly mounted on the pump side of the container. This results in When concrete is delivered, concrete splashes generated in the material supply container are exposed to the machine area. does not reach. However, effective flight is only possible if the structural height of the thin board box is sufficient. It was found that droplet prevention could not be achieved. This, on the other hand, is due to the amount supported by the chassis. Sufficient free space is required below the distribution boom. This free space is especially large. This is not always the case with type distribution booms. Under running conditions, the material The filling opening of the supply container is often covered by a hopper cover formed from a rubber mat. It will be closed. As a result, concrete splashes may be scattered while driving, For example, concrete hardens quickly when exposed to sunlight.

これから出発して、本発明の根底をなす課題は、分配ブームの大きさに関係なく 、作業状態でも走行状悪でも効果的な飛沫防止を保証する、コンクリートポンプ 車の材料供給容器のだめの飛沫防止装置を開発することである。Starting from this, the problem underlying the invention is that regardless of the size of the distribution boom, , a concrete pump that guarantees effective splash protection in both working and poor running conditions. The purpose of this project is to develop a splash prevention device for the car's material supply container.

この課題を解決するために、請求の範囲第１項記載の特徴の組み合わせが提案さ れる。本発明の他の有利な実施形および発展態様は、請求の範囲従属項から明ら かである。In order to solve this problem, a combination of the features described in claim 1 has been proposed. It will be done. Other advantageous embodiments and developments of the invention emerge from the dependent claims. That's it.

本発明による解決策は、コンクリート飛沫を捕らえるために、ポンプ送出の間だ け、すなわちコンクリートポンプ車が停止し、分配ブームが持上げられていると きにのみ、飛沫防止装置が充分な構造高さを必要とするという思想から出発して いる。分配ブームが折り畳まれてブーム載置台に支持されている走行運転では、 　゛飛沫防止装置はこのような構造高さを必要としない。従って、本発明で（丈 、飛沫防止装置が材料供給容器のポンプ側の画成壁に設けられた、画成壁の開口 縁部から幾分突出している剛性のある壁構造物を備え、充填開口から離れた壁構 造物の上側縁部の範囲に、シャシ−に対して横方向に延びる水平な軸の回りに揺 動可能である揺動壁が枢着され、この揺動壁の揺動範囲が折り畳まれた分配ブー ムの揺動範囲と交差し、分配ブームがその支持個所から持ち上げられるときに、 充填開口の少なくとも一部にかぶさる走行位置から、この走行位置に対して約９ ０°だけ上方へ揺動した作業位置へ限定的に揺動可能であり、そしてこの両位置 で錠体可能である。この場合、揺動壁は二つの機能を有する。すなわち、作業位 置では、揺動壁は充分な高さの飛沫捕捉部材であり一方、走行位置では容器カバ ーとしての働きをする。揺動壁を支承するために必要な剛性のある壁構造物は、 構造高さが低くて済むので、ブーム載置台に分配ブームを支持するときに、分配 ブームは材料供給容器の充填開口の近くまで降ろすことができる。The solution according to the invention is that during pumping, in order to capture concrete splashes, i.e. when the concrete pump truck is stopped and the distribution boom is lifted. Starting from the idea that splash prevention devices require sufficient structural height, There is. In driving operation when the distribution boom is folded and supported on the boom mount, ゛Splash prevention devices do not require such a structural height. Therefore, in the present invention (length , an opening in the defining wall where the splash prevention device is provided in the defining wall on the pump side of the material supply container. A wall structure with a rigid wall structure projecting somewhat from the edge and away from the filling opening. In the area of the upper edge of the structure there is a oscillation around a horizontal axis extending transversely to the chassis.
